Easy to do.
Remove the sensor from the back of the valve on the outlet (attached to the end of the meter cable) and run a small magent up and down across the sensor, if the board shows water flow, it is a turbine issue. Depending on the age, water quality, and flow rates the meter regularly sees, the turbine can become worn. You can remove the turbine from the shaft and clean it carefully. An obstruction (gravel, debris, piece of wood etc) can cause the turbine to not spin under water flow as well.
The link in my signature shows you how to get to the meter.
